The wait to fix the airdrop issue has indeed been long.  Too long.  I apologize on behalf of the team for the wait.  We have made airdrop #4 live today, so folks can go ahead and claim it following the instructions.  The wrong GFN amount issues seem to have been corrected for most of the people that had any errors.  This here is also our last update that was published on June 27th.
